CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 565,689, dated August11 1896.

Application filed January 2, 1896- Serial No. 674,139. (No model.)

To aZZ whom if; may concern.-

Be it known that I, WiLLIAM E. Pnnnson, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Oar- Couplings, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to that class of carcouplings that areself-coupling; and it consists in a device by which the hooking-j aw ofthe coupling may be readily unlocked without requiring the attendant toplace himself i between the cars, the object being to add to thecertainty of working of the coupling and to save the attendants fromplacing themselves in dangerous positions. These objects I attain by themechanism shown in the accompanying drawings, in which Figure 1 is ahorizontal section showing one of the couplings in full lines and theother in dotted lines. Fig. 2 shows in side elevation the head of one ofthe couplings, a part being represented as broken out to show theconstruction of the locking device. Fig. 3 is a View partly in verticalsection and partly in elevation.

In the drawings, A A A represents the body part of one of the couplings.

B B is a yielding jaw pivoted to the body part at B and held in place bythe spring 13 The hooking-jaw H H is pivoted at II and is free to swingoutwardly on the pivot II when not locked. An opening H is made in thehooking-jaw H for convenience when. a link has to be used. Thecoupling-link is held by a pin which passes through the hole II.

The locking device consists of a block P, which is rigidly attached to apin P, the pin P being free to slide up or down, taking with it theblock P. The upper rear part of the hooking-j aw H is cut away, asindicated at H, so that it can freely turn or swing outwardly and unlockwhen the block P is raised up, as shown in Fig. 3; but when the block Pis lowered, as shown in Figs. 1 and 2, then the Shoulder H at the rearof the hooking-jaw will engage with the block P, and the hooking-jawwill be firmly locked in place.

My device for raising the block P consists of a rotatable shaft 0, saidshaft having at its inner enda boss 0 and a bent lever-arm 0 This bentlever-arm 0 extends downward, as shown in Fig. 2, the extreme endremaining below and away from the block P when the said block is in itslocking position. To cause the block P to raise up and unlock thehooking-j aw H II, the attendant has simply to place the bent end of ahand-rod into the hole 0' in the shaft 0 and turn it, causing the bentlever-arm C toswing under the block P and raise it up away from theshoulder H as shown in Fig. 3, and leave the hooking-jaw I-I free toswing outwardly and uncouple.

When the jaw His in its open position, the block P rests on the top ofthe shoulder H, but as soon as the hooking-jaw swings in to engage withthe corresponding jaw on the other car then the block P falls into itslooking position and the cars are self-coupled and locked.

I claim In a car-coupling the combination of a raise the saidlocking-block substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 30th day of December, A.D. 1895.
